Description of problem:
Let's assume that master audio volume level is at 50%.
Let's assume that Amarok player audio volume level is at 50%, so at the same level of master audio volume.
In this situation if you change the master audio volume level, Amarok player audio volume level will change too, at the same percentage. No problem till here.

Now you set a certain offset between Amarok volume level and master audio volume level, for example by decreasing Amarok by a 20%. Then try to change the master audio volume level, increasing or decreasing it quickly. You will ear audio crackling.

Disabling flat-volumes in /etc/pulse/daemon.conf solves the problem

Version-Release number of selected component (if applicable):
pulseaudio-6.0-8.fc22.x86_64
